IMPROVEMENT lN WHEELBARROWS.

Specification forming part of Letters Patent No. 216,999, dated July 1,1879; application filed May 5,

To all whom it may concern:

Be it known that I, HoLLIs CLARK, of the town of Stanstead, in thecounty of Stanstead and Province of Quebec, Canada, have inventedcertain new and useful Improvements in Wheelbarrows; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itapper tains to make and use the same, reference being had to theaccompanying drawings, and to letters of reference marked thereon, whichform a part of this specification.

My invention relates to wheelbarrows; and consists, first, of aswingingend-board, in combination with a hinge so constructed as to permitvertical motion'while unloading; and, secondly, in the manner ofconstructing the frame, whereby the wheel is brought under the frame, sothat more weight is brought thereon, thus enabling the operator to wheela much heavier load.

In the accompanying drawings, in which similar letters of referenceindicate like parts, Figure 1 is an elevation of a device em bodying myinvention; and Fig. 2 is aview of the same, showing it as in the act ofunloading.

The frame A and side-boards B may be made in the ordinary manner, withthe excep-.

tion of the inclined parts 0, which are so placed as to carry at theirlower extremities the bearings a, and attheir upper extremities the rod1), forming a portion of the, hinge a. By the peculiar shape of theparts 0 it also serves as a stop for the swinging end-board D, and as arest for the side-boards B, at the same time bringing the single wheel Fso far beneath the body of the wheelbarrow as .to greatly facilitate thewheeling of heavy loads.

, The hinge consists of the horizontal rod 1), in-

closed by the long vertical staple 0. This kind of hinge permits theend-board D to have ver tical play. the length of the staples c, andobviates the danger of trigging when unloadin g, which would otherwiseobtain.

In order to keep the end-board D in the position proper for retainingthe load, a rod, E, is provided, working in bearings g g, one of whichfits in a circular groove in rod E, thus preventing end play of the saidrod, the forward end being turned at right angles to form the hook d,and the back end, 0, bent in any form suitable for being operated by thehand or knee. The lower front edge of the end-board D is shod with aplate of iron, f,

ator when occupying a position between the handles, substantially as andfor the purpose set forth.

2. In a wheelbarrow, the parts 0, connected at their upper ends by therod 1), in combination with the end-board D, having elongated staples c,inclosing said rod b, and rod E, substantially as and for the purposeset forth.

3. In a wheelbarrow, the end-board D, having the staples c, incombination with the parts 0, having the rod 1), and rod E, work ing inbearings g g, having its outer end bent at a right angle, substantiallyas and for the purpose set forth.

4. In a singlewheeled wheelbarrow, the rod E, provided with the book 01,and revolvingin the bearings gg, in combination with the endboard D, andoperating substantially as set HOLLIS GLARK.
